A drain arrangement in which the cover grating 1 of the drain can be easily lifted for cleaning. When a push button or the like located at the centre point of the cover grating 1 is pressed down, a projection 7 emerges from the cover grating 7 as a result of the levering mechanism 3, 4, 5 situated under the cover grating. By pulling the said projection up, it is possible to release the cover grating for cleaning purposes. When the lifting mechanism 2, 3, 4, 5, 6, 7 is in the rest position, the projection 7 lies below the surface of the grating and there is no part above the grating surface. <IMAGE> |
